X11 logout on display :0 messes the behaviour of other X11 displays running at the same time
How to run two X sessions at the same time?lubuntu won't display on both monitors at the same timeShift running X window (display environment) on SSH X11 forwardingx11vnc server with Xubuntu show black screen in clientX11 lets me change to other resolutions, but only the first time the system startsvncserver remote session grey screen ubuntu 16.04what are the remote sharing servers available for x11 display in ubuntu 16.04Ubuntu 16 behaves in different way whith two displays at the same timeX11: How to disable the combined display desktop, so screens can be adressed with DISPLAY=:0.x(ZaphodHeads) X11 display does not work from the beginning
Working on any of the conventional desktop environments (KDE, mate, cinnamon, etc, wich usually run on the display :0 ), I am able to successfully launch a vnc xserver on display :1, and connect to it using a vncclient. As the vncserver works in the background, it continues to work even if I log out the (ie. KDE) session on display :0 .
After such a log out, :1 is still running, and I can connect to it again. However this time, trying to launch any graphical program inside the vncsession is not possible, and every application complains saying that they cannot connect to the :1 display:
$ xterm
No protocol specified
xterm: Xt error: Can't open display: :1
$ terminator
No protocol specified
/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:57: GtkWarning: could not open display
warnings.warn(str(e), _gtk.Warning)
You need to run terminator in an X environment. Make sure $DISPLAY is properly set
Albeit they say that the $DISPLAY envvar is not set, it is correctly set indeed:
echo $DISPLAY
:1
I especulate that the logout procedure on :0 messed something (perhaps the X11 sockets for :1) in the vncserver, preventing newer applications to connect to :1, however, but I have not been able to figure it out.
This happens regardless the vncserver implementation (vncserver, vnc4server, tightvncserver.. etc).
Similarly, other remote display solutions as xpra get messed after logout, for instance display :100 get inaccessible, and xpra attach cannot connect, despite it still continues running in background.
Any ideas of what is causing this?
